Right and down are the correct answers - use your right hand rule.
C. Thumb pointing out of the page (direction of the current), fingers pointing down (magnetic flux) and thus, palm facing to the right (force).
D. Thumb pointing into the page (direction of the current), fingers pointing to the right (magnetic flux) and thus, palm facing down (force).
Just so you know, this is the right hand palm rule: http://upload.wikimedia.org/wikipedia/commons/6/6f/Right_Hand_Rule_vBF2.PNG
Where:
F=force (palm)
B=magnetic flux
v=direction of positive charge OR direction of conventional current
